Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00425 | $0.00425 |
| Opus 5.5 | $0.00170 | $0.00170 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
feima-copilot-llms-extension copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Feima Copilot LLMs Extension - Copilot Instructions
Localization
This extension has two separate and distinct localization systems. Do not mix them up.
1. Runtime strings — l10n/bundle.l10n.zh-cn.json
Used for strings displayed at runtime from TypeScript code via vscode.l10n.t().
Key rule: the key IS the full English string, not a short identifier.
// ✅ Correct — full English string as key
vscode.l10n.t('Signed in as {0}', session.account.label)
vscode.l10n.t('Please sign in to Feima first')
// ❌ Wrong — short identifier keys do NOT resolve to translations
vscode.l10n.t('error.signIn')
vscode.l10n.t('message.loggedIn')
When adding a new runtime string:
- Use the full English text as the
vscode.l10n.t()argument - Add the translation to
l10n/bundle.l10n.zh-cn.jsonwith the same full English string as the key:
{
"Signed in as {0}": "已登录为: {0}",
"Please sign in to Feima first": "请先登录 Feima 账号"
}
2. Manifest strings — package.nls.json / package.nls.zh-cn.json
Used only for static strings declared in package.json contributions (commands, settings, etc.) via %key% syntax.
// package.json
{ "title": "%command.signIn.title%" }
// package.nls.json (English default)
{ "command.signIn.title": "Sign In" }
// package.nls.zh-cn.json (Chinese translation)
{ "command.signIn.title": "登录" }
These keys are never used in TypeScript code. vscode.l10n.t('command.signIn.title') would display the literal string "command.signIn.title" — not the translation.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
